What is the difference between 6V PSU and 12V PSU

Updated

With 6V PSU the hub can run on an external battery for years — without being connected to the facility’s electric grid — and be ready to protect run-down or empty premises, as well as buildings under construction against burglars, vandals and unauthorized occupants.

12V PSU is used to connect the hub to the low-voltage network of a car, trailer, yacht or to power it from an external battery/power supply.
